Closed orbit errors and correction in the SXLS ring
SXLS is an electron synchrotron/storage ring, used as an X-ray lithography source, with a critical wavelength of {lambda}=10 A. It has a circumference of 8.5 m and its main elements are two 180{degree} combined function dipole, four quadrupoles and two sextupoles. The horizontal and vertical tunes are 1.415 and 0.415, respectively. The machine is being constructed in two phases. In Phase 1 and 2 it will run at 200 and 696 Mev using conventional (warm) and superconducting bending magnets, respectively. All other elements, as well as the lattice functions will be the same in the two phases. The constraint that the exit slits impose on the photon beamlines, requires that the source point, that is the closed orbit be controlled to better then {plus minus}3 mm horizontally, {plus minus}2 mm and {plus minus}1 mrad vertically. The following is a study of the expected closed orbit distortion in the ring as well as of the orbit monitor/corrector schemes necessary to correct the orbit. 10 figs.
